Talk to Cavemen!

cavemenThat title is used in a Washington Post article this week about a recent article in the field of historical linguistics published in the Proceedings of the National Academy of Sciences, which claims to trace a group of words back through seven different language families to a common ancestor language spoken some 15,000 years ago. Historical linguists use cognates (words with similar sounds and meanings) to trace language evolution and are able to compare cognates that appear to be related in a variety of language back to common ancestral languages.  The best-known example is Proto-Indo-European, an ancestor of a number of language families in contemporary Europe and India.

Mark Pagel (University of Reading) and collaborators built a sophisticated statistical model to try to identify specific words across language families that are similar enough, they believe, to have had a common origin. They found 23 “ultraconserved” words. Some which one might expect, including hand, give, I, thou, old and mother, but some which may be surprising such as spit, worm, and bark (of a tree).  The original Washington Post article imagines what might have been said with these words:

You, hear me! Give this fire to that old man. Pull the black worm off the bark and give it to the mother. And no spitting in the ashes!

It’s an odd little speech. But if you went back 15,000 years and spoke these words to hunter-gatherers in Asia in any one of hundreds of modern languages, there is a chance they would understand at least some of what you were saying. That’s because all of the nouns, verbs, adjectives and adverbs in the four sentences are words that have descended largely unchanged from a language that died out as the glaciers retreated at the end of the last Ice Age.

As intriguing as this theory is, many linguists are skeptical, as nicely explained by Sally Tompson on the Language Log. So maybe don’t count on being able to communicate with a caveman if you encounter one.

Cheap lunch

US Treasury Secretary Lew at a Beijing dumpling restaurant

New US Treasury Secretary Jack Lew, on an official visit to China, was spotted eating at a dumpling restaurant in Beijing.  One wouldn’t think that would be newsworthy, but it is created a stir in China.  Why?  Because government ministers in China would not consider eating at such a modest establishment.  Total cost for Lew and two colleagues for lunch:  less than $20 (109 yuan).  While such actions as this, and similar behavior by US government officials, such as new US China ambassador Gary Locke buying a coffee with a coupon while carrying his own bag, have brought praise on Sina Weibo (the Chinese Twitter) from ordinary citizens, some Chinese officials are complaining that US officials are trying to embarrass them by their conspicuous non-consumption.  This is all the more stinging for Chinese officials who, under new national leadership, are fighting against perceptions of corruption, cronyism and opulent living on the part of party officials.

Of course, American politicians tend to make a show of being one of the people, in line with American egalitarianism and populism.  In China, despite an official communist “government of the people”, different behavior and treatment based on social status is a long-standing aspect of Chinese culture.  However, with the rise of social media, which has spread fast and widely stories of abuse of power by party officials (and sometimes their offspring), the traditional respect for higher-ups is waning, while the admiration for the modest behavior of US officials is on the rise.

Norwegian wood

Lars Mytting wrote “Solid Wood" & inspired a TV program about firewood.

Lars Mytting wrote “Solid Wood” & inspired a TV program about firewood

There have been several stories in the media (NT Times: Bark Up or Down? Firewood Splits Norwegians) recently about a cultural phenomenon that may strike outsiders as very foreign, the importance of how firewood should be stacked. The stories were inspired by the enormous popularity in Norway of a book about firewood (Solid Wood by Lars Mytting) and also of a prime-time TV show on the same topic.  The TV show focused on chopping and stacking wood and was watched by over a million viewers (out of a total population of 5 million), but it also caused considerable controversy – a number of viewers contacted the station complaining that how the wood was being stacked was all wrong.  It turns out that there are strong feelings in Norway about how the stacked firewood should be oriented in reference to its bark, whether the bark should face up or down, so as to aid in faster drying.

The TV special was actually 12 hours long, with the first 4 hours showing and discussing wood cutting and stacking, with the final 8 hours showing live a fire in a fireplace in a Bergen farmhouse.  Through the hours, one could see wood being added and sausages being roasted on sticks, but no sounds were heard other than the burning of the fire.  One comment reported by NY Times article: “’I couldn’t go to bed because I was so excited’, a viewer called niesa36 said on the Dagbladet newspaper Web site. ‘When will they add new logs? Just before I managed to tear myself away, they must have opened the flue a little, because just then the flames shot a little higher…I’m not being ironic,’ the viewer continued. ‘For some reason, this broadcast was very calming and very exciting at the same time.’”  Such sentiments were not universal, however, as the article reports: “On Twitter, a viewer named Andre Ulveseter said: ‘Went to throw a log on the fire, got mixed up, and smashed it right into the TV.’”

The last time Norway was in the news was for something diametrically opposed to the program’s images of peace, calm and simplicity, namely the deadly rampage by Anders Brevik in Oslo in 2011, resulting in 77 deaths. The popularity of the firewood book and TV special may be related to the aftermath of this event, which caused considerable soul-searching in Norway.  Wood burning stoves and the cultural practices that surround their use have a long tradition in a country with long and severe winters.  Firewood culture harkens back to a traditional Norwegian way of life, free from the violence and political strife of the world today.

Words and Genes

A Turkish origin for Indo-European languages

A possible solution to one of the thorny questions in historical linguistics – where was the ancestor of many European and Indian languages of the Indo-European language family spoken – has been proposed using techniques normally enlisted in battling disesases.  According to findings recently published, the parent “Proto Indo-European” originated in the Anatolia region of present-day Turkey.

The techniques used actually go back to work in 2003 by Russell Gray and Quentin Atkinson at the University of Auckland in New Zealand:  ” Genes and words have several similarities, and language evolution has conventionally been mapped using a “family tree” format. Gray and Atkinson theorized that the evolution of words was similar to the evolution of species, and that the ‘cognate’ of words — how closely their sounds and meanings are related to one another — could be modelled like DNA sequences and used to measure how languages evolved.

By extension, the rate at which words changed — or mutated — could be used to determine the age at which Indo-European languages diverged from one another.” (Nature)  The new study adds to the information about when the ancestor language was spoken with the new geographical information, by using ” the type of geography-based computer modelling normally used by epidemiologists to track the spread of disease” (Nature).  Not all linguistis are convinced but as Aktinson comments in the article, it does point to a shift in acceptance of new methodologies in languistic research, indicating a “shift in attitudes towards computational-modelling approaches in historical linguistics, from being just an odd sideshow to a clear focus of attention”

Culture? There’s an app for that

Gee, all you need for knowing about other cultures, right on your smart phone.  The CultureGPS app allows you to call up one of over 100 countries/regions and have a score displayed on how that culture ranks in terms of Gert Hofstede’s five cultural dimensions:  power distance, individualism, masculinity, uncertainty avoidance, and long-term orientation.  The paid version (25$) allows for comparing the scores of two cultures. In the FAQ on their Web site, they admit that individuals from the target cultures do not necessarily reflect the scores shown, but they don’t mention variations based on region, membership in minority ethnic groups, gender, age, all of which can be significant.

On possible cultural change that might affect the accuracy of the information, the FAQ says that “On principle, culture is very stable” but does admit that catastrophic events might cause some variations.  I would categorize culture as dynamic and cultural identity as being influenced these days by so many factors, especially on-line roles and personas, that it is a complex issue.  Their disclaimer may point to the real usefulness of the app, namely to drum up business for their training seminars:  “The information contained in CultureGPS is intended as a guideline and for creating awareness. Proper use can only be assured when having undertaken one of our intercultural management trainings. Its use by those who have not received such training may result in error.”
